Presence-Based Power Management

ABSTRACT

The illustrative embodiment describes a system that manages the energy usage of a user&#39;s appliance based on: (i) the user&#39;s location, and (ii) the user&#39;s “presence information.” The “presence information” of a user is defined as a status indicator that includes, but is not limited to: the ability and willingness of a user to communicate and a user&#39;s mood. For example, when a user is lonely and at work, the office door should open, but when the user is not lonely and at work, the user&#39;s instant messages should be shut off. The illustrative embodiment comprises: an appliance; and an energy-usage controller for de-activating an energy-consuming element of the appliance based on presence information of a user of the appliance.

FIELD OF THE INVENTION

The present invention relates to energy management in general, and, more particularly, to the use of location and presence information to manage energy-consuming elements.

BACKGROUND OF THE INVENTION

Energy is expensive, and, therefore, the need exists for more energy-efficient products.

SUMMARY OF THE INVENTION

The present invention provides a technique for energy management that avoids some of the costs and disadvantages of the prior art. For example, the illustrative embodiment manages the energy usage of a user's appliance based on: (i) the user's location, and (ii) the user's “presence information.”

For the purposes of this specification, the “presence information” of a user is defined as a status indicator that includes, but is not limited to: the ability and willingness of a user to communicate and a user's mood.

In accordance with the illustrative embodiment, when a user is lonely and at work, the office door should open, but when the user is not lonely and at work, the user's instant messages should be shut off. Similarly, when a user is at home and lonely, the user's robot dog should activate, but when the user is at home and not lonely, the robot dog should return to its charging base.

Also in accordance with the illustrative embodiment, if a user is at home and is bored, the user's television should turn on, but if the user is at home and not bored, the television should do nothing—the television should neither activate if it is off nor should it de-activate if it is on. If the user is away from home and is bored, the user's portable music player should activate, but if the user is away from home and is not bored, the portable music player should do nothing.

The illustrative embodiment comprises: an appliance; and an energy-usage controller for de-activating an energy-consuming element of the appliance based on presence information of a user of the appliance.
